Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
nang hang » nang sang, hang hang, cang thang
duong van » duong va, luong va, dang van
van thanh » ban thanh, van tuan
thanh tap » thanh lap, thanh tai, thanh tay
doi lieu » duoc lieu, doi chieu, du lieu
va dong » van dong, xa dong, lao dong
ha dong » hoat dong, van dong

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi lieu tinh - nang hang ((va dong) OR (ha dong)) duong van thanh tap~".
• Adding a wildcard symbol may retrieve word variants: doi lieu tinh - nang hang ((va dong) OR (ha dong)) duong van thanh tap*.
